the locking block 5, the rotating shaft 13, and the first elastic
member 7 are arranged in the quick mounting groove; the
transmission arm 6 is rotationally connected to the second
connector through the rotating shaft 13, the locking block 5 is
provided on the transmission arm 6, and the locking block 5 is
configured to lock the quick mounting block 2 which has entered the
quick mounting groove; and the first elastic member 7 is connected

[0062] In the present embodiment, the first connector is configured
to connect photographic equipment, or the photographic equipment is
taken as the first connector, and likewise, the second connector is
configured to connect pan-tilt, or the pan-tilt is taken as the
second connector.
[0063] In the present embodiment, the self-locking mechanism
includes two parts provided on the first connector and the second
connector, respectively, and when the two parts of the self-locking
mechanism are fixedly connected, fixed connection between the first
connector and the second connector may be just realized.
[0064] Specifically, in the present embodiment, the two parts of
the self-locking mechanism are the quick mounting block 2 provided
on the first connector, and the locking block 5 provided on the
second connector, respectively, and the first connector and the
second connector are fixedly connected together after the quick
mounting block 2 is locked by the locking block 5.
[0065] More specifically, in the present embodiment, the locking
block 5 is connected to the rotating shaft 13 through the
transmission arm 6, so that the locking block 5 can rotate around
the rotating shaft 13, and locking and unlocking of the quick
mounting block 2 are realized through bidirectional rotation of the
locking block 5.
[0066] In the present embodiment, the first elastic member 7 is
provided on the locking block 5 or on the transmission arm 6, so
that the stability of the locking block 5 on the quick mounting
block 2 can be ensured when the locking block 5 locks the quick
mounting block 2; and when the quick mounting block 2 is being
installed, after the locking block 5 is squeezed open by pressure,
the locking block 5 can be reset under the action of the first
elastic member 7, thus realizing the locking of the quick mounting
block 2.
[0067] In an optional embodiment, the quick mounting block 2 is
provided with a first mounting surface 19 and a second mounting
surface 20 which are oppositely arranged; the first mounting
surface 19 is fitted to a side wall of the quick mounting groove,
and the second mounting surface 20 is fitted to the locking block
5; the first mounting surface 19 is an arc-shaped surface or a
plane; and the second mounting surface 20 is provided symmetrical
to the first mounting surface 19.
[0068] Specifically, in the present embodiment, two side surfaces
provided opposite to each other on the quick mounting block 2 are
mounting surfaces, which are fitted to the side wall of the quick
mounting groove and the locking block 5, respectively.
[0069] Specifically, in the present embodiment, the cross-sectional
shape of the quick mounting block 2 is isosceles trapezoid. In this
case, two inclined surfaces of the quick mounting block 2 are the
first mounting surface 19 and the second mounting surface 20,
respectively, and a short side of the isosceles trapezoid is
connected to the first connector.
[0070] It should be indicated that the cross-sectional shape of the
quick mounting block 2 may be isosceles trapezoid, while it is not
merely limited to the isosceles trapezoid, but may also be other
shapes having an inclined side, as long as the quick mounting block
2 is locked through cooperation between the locking block 5 and the
second mounting surface 20.
[0071] More specifically, in the present embodiment, the shape of
the quick mounting block 2 is a square tapered shape, with a
relatively small bottom surface connected to the first
connector.
[0072] In the present embodiment, the first mounting surface 19 and
the second mounting surface 20 are both planes, and they may also
be provided as arc-shaped surfaces, and meanwhile, the side wall of
the quick mounting groove and a side surface of the locking block 5
close to the second mounting surface 20 are also correspondingly
adjusted according to the shapes of the first mounting surface 19
and the second mounting surface 20.
[0073] That is to say, the first mounting surface 19 and the side
wall of the quick mounting groove are fitted in the self-locking
state of the quick mounting block 2, and the second mounting
surface 20 and the surface of the locking block 5 are fitted in the
self-locking state of the locking block 5.
[0074] On a symmetrical plane of the first mounting surface and the
second mounting surface, a direction perpendicular to an axis of
the rotating shaft is a first direction; and the rotating shaft is
provided in a projection region of the quick mounting block in the
first direction within the quick mounting groove.
[0075] Specifically, in the present embodiment, the rotating shaft
13 is provided in the projection region of the quick mounting block
2 in the first direction, and after being installed into the quick
mounting groove, the quick mounting block 2 is locked by the
locking block 5, and the position of the locking block 5, the
position of the quick mounting block 2, and the position of the
rotating shaft 13 form an acute triangle, as shown by the triangle
in FIG. 5, in turn, the locking of the locking block 5 to the quick
mounting block 2 is the most stable.
[0076] In the present embodiment, the position of the locking block
5, the position of the quick mounting block 2, and the position of
the rotating shaft 13 may be centers of gravity of the three,
respectively, or in a certain cross section simultaneously having
the three, geometric centers, geometric centers of gravity of the
three, and the like.
[0077] In an optional embodiment, when the first mounting surface
19 is a plane, on a fitting surface 21 after the second mounting
surface 20 and the locking block 5 are fitted, an edge line away
from the first connector is a contact reference line, and an
included angle .alpha. between a plane jointly determined by the
axis of the rotating shaft 13 and the contact reference line and
the fitting surface 21 is:
45.degree..ltoreq..alpha..ltoreq.100.degree..
[0078] Specifically, in the present embodiment, when the first
mounting surface 19 and the second mounting surface 20 are both
planes, among edge lines of the fitting surface 21 formed between
the second mounting surface 20 and the locking block 5, the edge
line away from the first connector is defined as the contact
reference line. In the above, in the present embodiment, the
contact reference line is a straight line, and the contact
reference line is parallel to the axis of the rotating shaft 13, so
that the contact reference line and the axis of the rotating shaft
13 can be arranged on the same plane, i.e. one plane can be
determined by the contact reference line and the axis of the
rotating shaft 13. In the present disclosure, this plane is defined
as a moment surface 22, as shown in FIG. 4.
[0079] In the present embodiment, the included angle .alpha.
between the moment surface 22 and the fitting surface 21 between
the second mounting surface 20 and the locking block 5 has the
following relationship:
45.degree..ltoreq..alpha..ltoreq.100.degree., so that the rotating
shaft 13 can give the locking block 5 a self-locking force towards
the direction of the quick mounting block 2, thereby ensuring the
stability of self-locking.
[0080] Specifically, as shown in FIG. 3, when the force is analyzed
on the fitting surface 21, a locking force applied by the locking
block 5 to the quick mounting block 2 is F.sub.0 towards the lower
left, which may be divided into a component force F.sub.1 in a
horizontal direction and a component force F.sub.2 in a vertical
direction, in this case, the quick mounting block 2 will give a
reacting force F'.sub.0 to the locking block 5, and F'.sub.0 is
divided, then a reverse horizontal component force F'.sub.1 and a
reverse vertical component force F'.sub.2 may be obtained. In this
case, the direction of the reverse horizontal component force is
the direction away from the quick mounting block 2, and the
position of the rotating shaft 13 connected to the locking block 5
through the transmission arm 6 is in the direction of the locking
block 5 close to the quick mounting block 2, further the rotating
shaft 13 locks the locking block 5 through the transmission arm 6,
thereby avoiding the locking block 5 from moving towards the
direction away from the quick mounting block 2, and achieving the
self-locking function of the locking block 5.
[0081] Therefore, when the angle of .alpha. is
45.degree..ltoreq..alpha..ltoreq.100.degree., the self-locking
force of the locking block 5 can be ensured, and the stability of
the locking block 5 in self-locking is ensured.
[0082] Preferably, in the present embodiment,
80.degree..ltoreq..alpha..ltoreq.90.degree..
[0083] In an optional embodiment, the self-locking mechanism
further includes an unlocking structure, and the unlocking
structure is configured to unlock the self-locking mechanism after
self-locking.
[0084] After the self-locking mechanism locks the quick mounting
block 2, in order to realize unlocking of the quick mounting block
2, and further to realize the dismounting function, on the basis of
the self-locking mechanism, the unlocking structure is further
provided.
[0085] Specifically, in an optional embodiment, the unlocking
structure includes an unlocking arm 11, the unlocking arm 11 is
connected to the transmission arm 6, and the unlocking arm 11 is
configured to drive the transmission arm 6 to rotate to realize an
unlocking function.
[0086] In the present embodiment, the unlocking arm 11 is connected
to and provided on the transmission arm 6, and by pulling the
unlocking arm 11, the transmission arm 6 can be driven to rotate
around the rotating shaft 13, so as to drive the locking block 5 to
move, thus finally achieving the purpose of removing the quick
mounting block 2.
[0087] Specifically, in the present embodiment, one end of the
unlocking arm 11 is fixedly connected to one end of the
transmission arm 6 away from the locking block 5, and both ends are
rotationally connected to the rotating shaft 13.
[0088] More specifically, a rotation sleeve 12 is rotationally
provided on the rotating shaft 13, one end of the unlocking arm 11
is fixedly connected to an outer wall of the rotation sleeve 12,
and one end of the transmission arm 6 away from the locking block 5
is also fixedly connected to an outer wall of the rotation sleeve
12, in turn when the unlocking arm 11 rotates, the transmission arm
6 will be driven by the rotation sleeve 12 to rotate around the
rotation sleeve 13.
[0089] In an optional embodiment, the unlocking structure further
includes an unlocking member 10; the second connector is provided
with an unlocking hole 17, and the unlocking hole 17 is in
communication with the quick mounting groove; the unlocking member
10 is slidably provided in the unlocking hole 17, and the unlocking
member 10 abuts against the unlocking arm 11; the unlocking member
10 is configured to drive one end of the unlocking arm 11 away from
the rotating shaft 13 to rotate around the rotating shaft 13.
[0090] In the present embodiment, the rotating shaft 13 is provided
on the second connector, which is relatively farther from the outer
surface of the second connector, so that when unlocking is
performed through the unlocking arm 11, rotation amplitude of one
end of the unlocking arm 11 away from the rotating shaft 13 is
relatively large.
[0091] In order to solve the above problem, in the present
embodiment, the unlocking member 10 is added, and the unlocking arm
11 is driven by the unlocking member 10 to rotate about the
rotating shaft 13, further driving the transmission arm 6 and the
locking block 5 to rotate around the rotating shaft 13, thereby
finally achieving the unlocking function.
[0092] Specifically, in the present embodiment, the unlocking
member 10 is inserted into the quick mounting groove through the
unlocking hole 17, and abuts against the unlocking arm 11, and the
unlocking arm 11 is driven to rotate through the sliding of the
unlocking member 10.
[0093] More specifically, in the present embodiment, the unlocking
member 10 is rod-shaped.
[0094] In an optional embodiment, an included angle .beta. between
an end surface where the unlocking member 10 abuts against the
unlocking arm 11 and the moving direction of the unlocking member
10 is:
0<.beta.<90.degree..
[0095] That is to say, in the present embodiment, the end surface
where the unlocking member 10 abuts against the unlocking arm 11 is
an inclined surface, and by providing the inclined surface, the
unlocking member 10 can be easily inserted between the unlocking
arm 11 and a groove wall or a groove bottom of the quick mounting
groove, that is, the unlocking arm 11 can be easily pushed to
rotate around the rotating shaft 13.
[0096] In a preferred embodiment, .beta.=45.degree..
[0097] Specifically, in the present embodiment, the unlocking
member 10 has one end being an inclined surface, and the other end
exposed outside the second connector. When an end portion of the
unlocking member 10 exposed outside is pressed, the unlocking
member 10 slides towards an inner direction in the unlocking hole
17, so that the inclined surface of the unlocking member 10 is
brought into abutment with the unlocking arm 11, the direction of
the force is converted by the inclined surface, further axial
movement of the unlocking member 10 is changed into rotation of the
unlocking arm 11 around a central axis, and then the transmission
arm 6 is driven to rotate through the rotation of the unlocking arm
11, and finally the locking block 5 is driven to be separated from
the quick mounting block 2, thus realizing the dismantling function
of the quick mounting structure.
[0098] More specifically, in the present embodiment, the inclined
surface is a planar structure.
[0099] It should be indicated that the inclined surfaces may also
be provided in a structural shape such as arc shape, as long as the
purpose of driving the unlocking arm 11 to rotate can be realized

elastic member, the normal state of one end of the unlocking member
10 away from the unlocking arm 11 is exposed outside the second
connector, and one end of the unlocking member 10 close to the
unlocking arm 11 and the unlocking arm 11 are in a normally open
state. That is to say, under the action of the second elastic
member, when the unlocking operation is not performed on the
unlocking member 10, an outer end thereof is always exposed outside
the second connector, and an inner end thereof is not in contact
with the unlocking arm 11.
[0102] When the unlocking operation is performed, the unlocking
member 10 is pressed to enable it to move inwards, and after the
unlocking member is in contact with the unlocking arm 11, the
unlocking arm 11 is driven to rotate, to separate the locking block
5 from the quick mounting block 2, thus realizing the unlocking
function; after the unlocking is completed, the unlocking member 10
is released, and the unlocking member 10 is reset under the action
of the second elastic member, that is, the unlocking member is
restored to an initial position, and kept in a state that the outer
end is exposed, and the inner end is separated from the unlocking
arm 11, so as to facilitate the unlocking operation again.
[0103] Specifically, in the present embodiment, the second elastic
member may be a pressure spring, a pulling spring, a torsional
spring, an elastic sheet, etc., as long as the second elastic
member has certain elasticity, and can enable the unlocking member
10 to be reset after the unlocking function is realized.
[0104] It should be noted that, in the present embodiment, the
unlocking arm 11 is driven to rotate by pressing the unlocking
member 10, and further the unlocking function is implemented, but
the unlocking manner is not limited thereto, for example, the
unlocking manner further may be as follows: the transmission arm
may be directly acted on through a key, to drive the transmission
arm to rotate for unlocking, wherein the key may be manually
pressed, or automatically pressed by a cylinder, an oil cylinder or
the like, as long as the unlocking of the self-locking mechanism
can be realized through the unlocking structure.
[0105] In an optional embodiment, the quick mounting groove is
provided therein with a limiting portion, and the limiting portion
is provided in the quick mounting groove on the second connector;

limiting portion not only can define the depth of the quick
mounting block 2 which has entered the quick mounting groove, but
also can prevent the quick mounting block 2 from being disengaged
from the quick mounting groove by an action such as turning in the
quick mounting groove, that is to say, the position of the quick
mounting block 2 in the quick mounting groove is limited at the
same time through the limiting portion.
[0107] In an optional embodiment, the limiting portion is the
limiting plate 18, and the limiting plate 18 is provided on the
side wall of the quick mounting groove; the limiting plate 18
divides the quick mounting groove into an upper limiting groove 15

vertical direction of the limiting plate 18 at the other end of the
limiting plate 18, that is, there is a gap between the limiting
plate 18 and at least one side wall of the quick mounting groove,
then the locking block 5 and the transmission arm 6 can be allowed
to be connected to the quick mounting block 2 above the limiting
plate 18 and the rotating shaft 13 below the limiting plate 18,
respectively, and there is a space for locking and unlocking the
locking block 5, further ensuring normal use of the apparatus.
[0109] Specifically, in the present embodiment, by providing the

and the other end connected to the locking block 5, and under the
action of the first elastic member 7, the locking block 5 can be
pushed into the upper limiting groove 15, so that the locking block
5 is brought into abutment with the quick mounting block 2, thus
realizing the locking to the quick mounting block 2, and further
realizing the locking between the first connector and the second
connector.
[0110] In the present embodiment, the unlocking hole 17 is in
communication with the lower driving groove 16, and the unlocking
member 10 abuts against the unlocking arm 11 through the unlocking

limiting plate 18, so that the locking block 5 and the transmission
arm 6 can pass through the hole in the limiting plate 18 to realize
locking and unlocking to the quick mounting block 2.
[0113] It should be indicated that the structure of the limiting
portion may be the limiting plate 18, but it is not merely limited
to the limiting plate 18, while it may also be other structures,
for example, an annular limiting strip provided on the side wall of
the quick mounting groove, or a plurality of limiting blocks
provided in a ring shape, as long as the locked position of the
quick mounting block 2 can be limited, and the locking stability of
the locked quick mounting block 2 can be ensured by providing the
limiting portion in the quick mounting groove.
